Sulfosalicylic acid is used in urine tests to determine urine protein content. The chemical causes the precipitation of dissolved proteins, which is measured from the degree of turbidity.^[1]

It is also used for integral colour anodizing.

With water it is used as a shuttle solution for the CAS assay to test for siderophore.
